Abstract: The invention relates to an antenna device having an emitter element for emitting and/or receiving electromagnetic signals. The emitter element includes at least one coupling point connected to a side of the emitter element, and implemented for capacitively coupling electromagnetic signals in and/or out.

Abstract: A phase shifter includes a signal input, a signal output, an ESD protection circuit, first and second signal paths between the signal input and the signal output. The ESD protection circuit includes first and second two port devices, each two port device being switchable between a high impedance state and a low impedance state. The first signal path includes the first two port device of the ESD protection circuit and a first delay line configured to provide a first phase shift to a signal transmitted from the signal input to the signal output via the first signal path. The second signal path includes the second two port device of the ESD protection circuit and a second delay line configured to provide a second phase shift, different from the first phase shift, to the signal transmitted from the signal input to the signal output via the second signal path.

Abstract: Embodiments provide a phased array antenna including a feed structure adapted to guide an electromagnetic wave, a plurality of controllable elements coupled to the feed structure and a plurality of radiating elements, wherein each of the radiating elements is coupled to at least two of the plurality of controllable elements.

Abstract: A method and apparatus for providing a continuously variable transmission (CVT) is described. The CVT comprises permanent magnets to couple power, a coefficient of coupling controlled by an electronic servo control loop. Wherein torque multiplication is achieved by “duty-cycle” modulation of the magnetic coupling “pulses”, between the input shaft and output shaft.

Abstract: A high-speed, fully-floating, current source/sink utilized a current mode operational amplifier to drive a power MOSFET without ringing or instability. The output of the current mode op amp is directly connected to the MOSFET gate. The current source relies on an optical link to enable an analog switch to generate carefully controlled pulse width characteristics at the positive input of the op amp.
